Question

solve x^2 -7x 14 years ago

Answer 1

\[x^2 -7x \le 0\]

Answer 2

Simplify the expression and solve for x.

Answer 3

x (x -7) < = 0

For it to be equal to zero either x = 0 or x - 7 = 0 <=> x = 7.

For it to be smaller than zero 0 < x < 7, because then x >0 and x - 7 < 0, and positive times negative is negative.
